. following is as ecification.

The object o my invention-is to produce a simple easily-manufactilredl pump especially y. deslgned for pumping lubricating-oil in small;

' regulateduantities from a reservoir to a part,to be ubricated.' ,The accompanying drawings invention.

Figure 1 is a vertical section of an embodiment of my invention on line 1 1 of Fig. 2; Fig. 2, a similar section on line 2 2 of Fig. 1

illustrate my Fig. 3, a side elevation; Fig. 4, an end elevation; Fig. 5, a section similar to Fig. 1 ci a double pump,rand Fig..46 a section on line 6 6 of Fig. 3.

In the drawings, 10 indicates a suitable reservoir of any desired size, within which is arranged a vertical cylinder 11, which is preferably formed integral with the reservoir 10, the borel of said cylinder being straight and entirely through the cylinder, so that it may be formed by 'an ordinary drill and its lower end closed by any uitable plug, such as the screw-plug 12. Intersecting the bore of cylinder 11 near its lower end a short distance above the plug'12 is Ya transverse passage 13, which also communicates at its inner end with the reservoir 10, the said passage thus forming, with relation to the bore of cylinder 1l, an-induction-po'rt 113 and an eductionptort 13 upon opposite sides of the' bore.

otatably and axially movable within the bore of cylinder 11 is a piston 14, the lower end of which is provided at one side with a longitudinal groove 15, the upper 'end of which extends-as far as the assage 13, so that it may communicate e1ther with` the port 13 or the port 13 and the lower end of which extends to the lower end of the piston. The piston is normally urged upward by means of a suitable spring 16, and it may be rotated and axially reciprocated by any suitable means.

.In Figs. 1 to 4, inclusive, I show a wabble bevelgear 17, pinned to the upper end of the piston and arranged so that the upper end of naled its hub will be engaged by the eccentric hub 18 of an eccentric bevel-gear 18, said gear 18 beinCr attached to a shaft 19, which is jourin the upper end of thereservoir 10 at right angles to the piston 14. By making thegear 17 a wabble-gear the eccentricity of the gear 18 may be half of the eccentricity of the eccentric 18. By this arrangement as 'shaft 19 is rotated the piston 14 will be simultaneously. rotated and axially reciprbcated, so that as thegroove comes op ite the induction-port 13 the piston 14 will be at its highest point and oil will flow from the reservoir l() through the induction-port 13 into the space 11 between the lower end oi"- the piston 14 and thc plug 12.' As the iston 14 1s rotated groove 15 is carried out oihegistry with the induction-port 13 and into registry with the eduction-port 13 and at the same time is moved, downward toward plug 12, so that the oil in the portion 11 of the bore of the cylinder will be forced upward (by the downward movement of the piston) and out through the eduction-port 13".

Any suitable means may be used for roshown a ratchet wheel or disk attached to the shaft 19. Swinging freely on shaft 19 between wheel 20 and casing 10 are two arms 21 and 22 the arm 21 being adapted to vbe reciprocated through a definite an le by any suitable means. In order that tie amount of angular advancement of the ratchet-wheel may be varied, even though the throw of arm 21 remains constant, I provide arm 22 with a pair of fingers 22' 22, arranged on opposite tating shaft 19. In the drawings I have i sides of ar'm 21 and spaced apart, so as to per# mit a limited independent movement of arm 21. Threaded through one finger 22 is a screw 22, by means of which the independent movement of arm 2lv may be limited..

Arm 22 carriles a spring finger or pawl 2 2, 'l

adapted to engage lthe teeth oi' the ratchet-l wheel- 19. By arranging the arms 21 and 22 between the casing 10 and wheel 19 I am able to provide wheel 19 with a handle 25, by means of which it may be readily turned by hand in case an initial supply of oil is desired to be discharged from the pump.

In the construction shown in Fig. 5 the pump construction is merely duplicated,

with the exception that the gears 17 are not- IDO - tion, a shaft', a cam carried by said shaft and wabble-gears. In order that the gears may l be assembled in proper relation, I provide f the gear 1.7 with a large or broad` tooth 17" and theA gear 18 with a corresponding broad space 18 between the teeth, so that the gears will. only run when assembled in proper positiono I claim as my inventionw I l'. The combination, with a suitable reservoir, of a cylinder formed integral therewith within the reservoir and having edu'ction and induction ports communicating with the bore thereof, a piston rotatably and axially reciprocable within the 'cylinder and having a passage formed therein communicating with the cylinder at the end ofthe piston and adapted to be brought into registry with theinduction and eduction ports successively, a spring for normally urging the piston in one direction, a shaft, a cam carried by said shaft and adapted to drive the piston axially in opposition to the spring, and a pair of meshing gears carried by the shaft and piston.
